SLEEVE non BEARINGS.

Application filed November .To all whom it may concern:

and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the-same, reference beinghad to the accompanying drawings, which form a part of this specification.

- My invention relates to sleeve bearing surfaces and an object of my improvements is to provide such a sleeve that shall fit closely to its adjusted position and be immovably held in place.

In the accompanying drawing, I have shown my invention as applied to an automobile axle.

Figure 1 is a sectional elevation of one end of an automobile axle with adjacent parts shown in section.

Fig. 2 is a section of the sleeve separate from the axle.

-Fig. 3 is an end View of the sleeve looking from the right of Fig. 2.

aindicates the axle of an automobile having the cylindrical part 01?, the conical part c and the screw-threaded portion ct in the order named. b is a nut on the screwthreaded portion a c is the wheel hub which is fitted to the conical part a of the axle and secured thereto by a key 0 the end of said key extends a short distance beyond the inner end of the hub c, for the purposes hereinafter described.

d is a bearing sleeve fitted upon the cylindrical portion a of the axle a. The outer end of this sleeve is cut away at 03 along its inner surface and slightly within the outer end of said sleeve. The extended cylindrical inner surface d of the sleeve 0Z fits upon the cylindrical surface a of the axle a. At the outer end of the sleeve (Z, the edge extends inward at d a short distance so that the diameter of the sleeve at this point is less than in the main portion 03. The inner surface of the sleeve at d is made slightly conical to fit against the conical surface a of the axle a. In the outer end of the sleeve 03 are formed three radial slots (2 extending inward to the cylinder 0! and past the cut-away portion d The 4, 1921. Serial No. 512,716.

outer end of said sleeve is also provided with a slot d The parts are assembled as follows:

The sleeve 03 is placed upon the cylindrical portion a of the axle at, its surface a? engaging against the cylindrical surface a of said axle and its surface (1 extending over and engaging against the surface of the conical portion at of the axle, as shown in Fig. 1. The hub c of the wheel is then placed in position upon the conical portion a of the axle, the key 0 engaging said hub and axle and extending beyond the "end of said hub, its end engaging in the slot (Z the nut?) is then adjusted to place and screwed up holding the hub c securely in position, the inner end of the hub engaging the outer end of the sleeve 03.

When the nut b is screwed up it will press .the sleeve 03 inward. The slots 03 d permit the outer end of said sleeve to expand as it is forced along the conical portion a of the shaft by the hub 0 forced inward by said nut. Thus a tight and close engagement between the sleeve and the axle is secured.

The engagement of the key 0 in the slot d will hold the sleeve d from rotation.

What I claimis:

1. The combination of an axle having the cylindrical portion a and the conical portion a coaxial with each other, and a sleeve adapted to fit upon said cylindrical portion of the axle and having an end of lesser di ameter adapted to engage upon the conical portion of said axle whereby said sleeve is positioned by the co-action of its smaller end and the conical portion of the axle.

2. The combination of an axle having the cylindrical portion a and the conical portion a coaxial with each other, and a sleeve adapted to fit upon said cylindrical portion ofthe axle and having an end of lesser diameter adapted to engage upon the conical portion of said axle, the end of said sleeve adjacent to the conical portion of said axlebeing constructed to afford elasticity in a radial direct-ion whereby said sleeve is positioned by the co-action of its smaller end and the conical portion of the axle.

3. The combination of an axle having the cylindrical portion a and the conical portion a and a sleeve adapted to fit upon said cylindrical portion of the axle and having an end of lesser diameter adapted to enend of said conical portion.

gage iipoii the "Ethical portionof said aide, the end 'of said sleeve adjacent tothe conical portion of said axle being constructed to afi'ord elasticity iharadial direction, and.

means for forcingsaid sleeve along said conical portion of the axle toward the larger 4. The combination of an aklejhaving the -end of said sleeve adjacent to the conical ip'ortion oi said axle being constructed to affordjelasticity in a radial direction, 'a Wheel hub-engagingupon said conicalport-ion of rthe axle hav ng its inner end engaging the outer end of. said sleeve,- and means for securing said, hub infposition and-forcing it inyvard for the purpose described.

. 5. The combination of anaxle having the cylindrical portion a and the conical portion a and asleevejadapted to [it upon said cylindrical portion of the axle and having an end of lesser diameter adapted to engage upon the conical portion of said axle, the outer end or said sleeve being provided with a radial slot, a Wheel engaging upon said axle .outside oi said sleeve, a key engaging said Wheel and axle,its end extending into said slot. i V

.6. The combination ofan aiile'liaving the cylindrical portion, a and the'conical portion, a coaxial with each other, and a sleeve adapted to fit upon said cylindrical portion of the axle, and having an end of lesser diameter adapted to engagejnpon the conical portion of said axle, the end of said sleeve adjacent to the conical portion of; said axle being provided with a plurality of radial slots. 7

In te st1inony whereof, I sign this specilicatlon.
